The driving medium may be a motor actu- In order to prevent the yarn coming into con- 55 tact with the motor, and to permit the unimpeded lateral displacement of the yarn, a second shell 65 in the interior of the split drum encloses the motor as nearly as possible. The motor 101 may be an electric motor of the usual kind with inside rotor and (outside stator), i. e. stationary field windings outside, the lengthened shaft 9 serving at the same time to carry the split drum 2. At its opposite end, the motor may be secured by a flange to a corresponding face of the bearing bracket 15 which may be specially developed for the purpose. '7 is the straight yarn guiding blade which is regularly used in connection with split drums. The electric circuit intended to drive the electric motor includes the contacts 50. When the creel bobbin 20 runs empty or the supply fails owing to the yarn breaking, the yarn detector 49, Fig. 1, swings to the left, its short counter-arm 49a, lifts-ofi the contact spring 50 and thereby interrupts the feed of the electric current to the motor, so that the split drum and the package 13 to be formed instantly stop, without requiring the hitherto necessary raising of the package 13 from the bobbin driving drum by mechanical means. In order to put a stop to winding on to the bobbin on the desired bobbin diameter being reached, the contact spring can also be raised by means of the adjustable collar 131 of a drawbar 130 hinged to the bobbin holder 14 with'its peg 132 and loosely projecting through a hole in the contact spring 50.

In the embodiment shown in Figs. 3 and 4, the package 13 to be formed is driven by surface friction from a winding drum 1, the shaft of which is rotatably carried in a bearing bracket 15. The winding drum 1 is itself driven over the yarn guiding drum 4 the surface of which has grooves for the to-and-fro movement of the yarn guide 6 sliding on a bar 6a. The yarn guiding drum 4 is designed to carry the rotary outside armature 62 of a rotary motor, the stationary inside field coils 63 of which are preferably mounted on a tube 61 secured to the bearing bracket 15, the-current being fed to the motor by the wiring arranged inside the tube 61. The end blocks 59 of the yarn guiding drum 4 can be made to turn on ball bearings 60 threaded on to the stationary tube 61. The 'operation of this embodiment is clearly visible from Figs. 3 and 4. The motor inside the drum 4 drives the winding drum 1 as well as the thread guide 6; the winding drum 1, in turn, driving the bobbin 13.

In the embodiment shown in Figs. 5 and 6, a hollow drum serves simultaneously as winding drum as well as yarn guide by means of the yarn uiding grooves arranged in its surface in known fashion. According to the present invention, a rotary outside armature 62 is utilized in similar fashion as the yarn guiding drum 4 in Figs. 3 and 4. The arrangement of the stationary inside field coils 63, the bearings of the hollow drum 3 and the feed of the current are here exactly the same as in the arrangement according to Figs. 3 and 4.

In the embodiment shown in Figs. '7 and 8, the split drum 2 again operates as driving means and simultaneously as the yarn guide for the package 13 to be formed. The rotary motor with its rotary outside armature 62 is fitted into the special shell 65, as in the embodiments shown in Figs. 3 to 6 which show also a similar arrangement for the stationary parts of the motor, the feed of the current and the fashion of bearing the split drum.

In the embodiment according to Figs. 9 and 10,

the rotary motor is built into the rotary boss of a rotary wing'yarn guide known initself. Two discs 58 can be arranged at the sides of the rotary wing yarn guide, for the purpose of driving the winding drum or shaft 1 by friction or by gear- The embodiment shown in Fig. 11 shows a spindle unit in which instead of the yarn mass the winding spindle is driven in known fashion. The cam 56a which carries on its surface the helical groove for the actuation of a yarn guide 6, carries in its interior the rotary motor described in the previously illustrated working examples. The .rotary motor transmits its motion through the gearing 1016, 101d and by way of example over a belt drive 1010, 1011) and 101a on to the spindle 12 with the package 13 to be formed.

In the embodiment according to Figs. 12 and 13, the motor is arranged inside the winding drum or shaft 1 in 'exactly the same fashion as described in the embodiments shown in Figs. 3 to 10. Here, the winding drum or shaft 1 drives the bobbin 13 to be formed as also the yarn guide roller 4. e

The embodiment shown in Figs. 14 and 15 show a split drum 2, again for the purpose of rotating the 'yarn mass body or package 13 and simultaneously guiding the yarn on to the latter, but inside the drum and accurately set in the special shell 65, the electric motor is replaced by a motor actuated by compressed air 70 which may be of any desired construction and which can also be replaced by one moved by some other fluid. The present working example shows a motor on the turbine principle for actuation by compressed air, which is fed by pipe '71, and after actuation of the motor blades and turning the split drum, leaves the turbine through a pipe '72.

The exhaust pipe 72 or suitable branches thereof can be made to guide the exhaust air to particular parts of the spindle unit where it cleans the parts in question from fluff and fly by a blowing action. The example shows for instance how the yarn guide 48 can be cleaned by-the exhaust air. If in place of the compressed air some other fluid is utilized as a means of actuating the motor, it is evidently necessary to provide for careful packing about the motor and the pressure piping and to guide the exhausted fluid into a common system.

Compressed air has been taken as an example because it is the cheapest fluid, but there is nothing in the way of using any other gaseous fluid or liquid for driving the motor. a
